To all whom it may concern:

Be it known that I, WILBERT T. BINTLIFF, a citizen of the United States, residing at Plainfield,in the'county of Union, State of New Jersey, have invented an Improvement in bustionl Engines, of which the following is aspecification.

Heretofore, in conjunction with an internal combustion engine, various forms of primers have been employed for initially ficiently heated to vaporize the fuel supplied thereto.

I am aware that heretofore in electric primers, various forms of switches have been employed for closing an electric circuit to the coil of the heater, and also heretofore, various forms of devices have been employed for supplying or forcing the liquid fuel to the heater to'be vaporized. In all instances, however, 'so'far as I am aware, these devices have been so made as to be separately operated, and in operating these devices separately, much inconvenience and oftendiificulty is experienced. The object .struction and use of my present invention.

Fig. 2 is a central longitudinal section of the primeractuating device to which the invention more particularly relates.

Fig. 3 is a cross section on line 3-3, ig. 2.

Fig. 7 is a cross section thereof. In carrying out the invention, as will'be seen by reference to the drawing, the primer actuating device to which the invention particularly relates, comprises a body member 10 which may be made of metal or any suitable material and is preferably cylindrical in form, and provided with a base 11 which closes one end ofthe cylinder. At the other end of the cylinder, the same is provided with a cover 12 having a flange 13 adapted to fit within the open end of the cylinder and by which, through means of screws 14 or otherwise,-the cover may be secured in'position in the cylinder. The base 11 is provided centrally with a tubular flange extending into the body member 10 and adapted to receive a shank 15 of a two way connection 16, the shank 15, as illustrated, being screw threaded to turn down into the bore of the tubular extension of the base 11, it being understood, however, that these parts may be otherwise connected without departing from the nature and spirit of this invention. The two way connection 16 is provided with stop valves 17' and 18, the formerof which permits the passage of the gasolene oriother liquid fuel in the direction of the arrow, while the latter also permits the passage of the liquid fuel in the direction of the arrow associated there.-

with, both stop valves preventing the flow .adapted to receive a plunger 20 'whlch, at

the Inner end thereof, is provided with areduced extension 21 fitted at its extremity with'a valve 22. This valve 22 which is of the needle valve type is adapted to bear against a valve seat 23 in the passage in the two way connection 16 leading to the stop valve 17 when the plunger 20 is in the dotted line position as indicated in Fig. 2 of the drawing. The reduced end 21 of the plunger 20 is screw threaded and fitted with a piston washer 24 which is maintained in position thereon by lock nuts 25 or otherwise. The piston washer is adapted to fit the bore in the shank 15 which thereby becomes a pump cylinder for drawing the liquid fuel from the source of supply and' primer as hereinafpasses, and in the outer wall of the cylindrical block 28, there is fixed a contact ring 30, the cylindrical block, as will be understood, being made of any suitable insulating material. The cylindrical block 28 in the operative positions of the parts of the apparatus is normally maintained in the full line position as shown in Fig. 2 with the head end of the block in contact with the inner surface of the cover 12 of the body member. This is accomplished by means of a spring 31 surrounding the plunger 20 and' extending between a shoulder 32 at the inner end of the tubular extension of the base 11 and the inner surface of the end 29 of the cylindrical block. A spring 33 also surrounds the plunger 20 and extends from the head 27 thereof through the opening 26 in'the cover 12 to the outer face of the end 29 of the cylindrical block. When the parts of the apparatus are in their operative positions as shown in Fig. 2 the tensions of the springs 31 and 33 are such that the action of the spring 33 will not overcome the action of the spring 31, whereas, when the parts are in their inoperative ositions or that shown in dotted lines in ig. 2, the tension of the spring 33 is sufficient to overcome the tension of the spring 31, thereby forcing the cylindrical block 28 away from the cover 12 of the body member to break the circuit to the heating unit as hereinafter described.

Within the body member 10 and fitted to the base thereof, I employ a ring 34 made of any suitable insulatin material. Secured to this ring 34, prefera 1y in oppositely disposed positions, there are terminals 35 and 36, these terminals being secured in position respectively by means of screws 37 and 38 or otherwise, the headsof which are preferably covered with insulating washers. The terminal 35 is provided with contacts 39 and the terminal 36 with contacts 40, the contacts 39 and 40 being adapted to bear against the ring contact 30 in the cylindrical block when the same is in its outermost position or with the head thereof in contact with the cover of the body member so that in thisposition, the circuit is closed through these contacts and the ring in the cylindrical block, and when the cylindrical block is in its other position, the circuit is broken by the ring moving away from the contacts.

- The stop valve 17 is connected by a pipe 41 to the inlet end of an electric heater or heating unit 42. This electric heater may be made in any suitable manner and preferably to contain a heat coil by means of which the liquid fuel supplied tothe heater is vaporized before passing to the manifold of the engine. As illustrated in Fig. 1, the heater 42 is connected at its discharge end to the intake manifold 43 of a motor. A pipe 44 leads from the stop valve 18 to a three way connection 45. One end of the three Wa connection 45 is connected by a pipe 46 lea ing from the supply tank for the liquid fuel, and the opposite end of the three way con nection 45 is connected by a pi e 47 to the inlet end of the carbureter emp oyed with the motor.

Oneend of the heat coil employed in the heater is connected to a terminal 48 situated on the exterior of the heater while the other end'of the heat coil is suitably grounded in the apparatus. A lead wire 49 extends through the base and through a hole 50 in the ring 34 and terminal 48 to the terminal 35. A lead Wire 51 extends through a hole 50' in the ring 34 and also through the base 11 and connects the terminal 36 to one terminal of a battery 52, the other terminal of which is suitably grounded in the apparatus. The body member 10 is provided with a flange 53 by means of which and screws 54 it may be secured in place in the dash board 55 of a car or in any other place.

The two way connection 16 is provided with a screw threaded socket 56 adapted to receive the reduced screw threaded end 21 of the plunger 20 so as to maintain the plunger in its imfiperative or dotted line position shown in ig. 2, and at the same time to cause the valve 22 to bear against the valve seat 1 23, in which position, as hereinbefore stated, the spring 33 counteracts the tension of the s ring 31 and forces and maintains the cyllndrical block in the position in which the circuit is broken at its contacts 39 and 40. 120 Now in o crating the device, the plunger is unscrewed so that the reduced end of the plunger is removed from the socket 56 and the plunger withdrawn and reciprocated. In withdrawing the plunger, the action of the 125 spring 31 forces the cylindrical block to its operative position, thereby closing the circuit through the contacts 39- and 40 and the contact ring 30 to the heater coil thereby heating the same, and by reciprocating the 180 megs plunger, moving the same back and forth, the piston washer 24: acting in the bore of the shank 15 draws the gasolene or other liquid fuel through the pipe 44 and valve 18 into the chamber in the shank 15 when the plunger is moved outwardly, and when moving the plunger in the opposite direction, the piston washer forces the liquid fuel thus drawn into the cylinder through the valve 17 and the; pipe 41 to the interior of the heater where it is vaporized before passingto the manifold of the motor.
